Vox has posted a cumulative graph of CO2 emissions since 1750. And the USA is flagged as the chief culprit. The actual title of the Vox article is:
Why the US bears the most responsibility for climate change, in one chart
It's unclear what the methodology is in establishing this, being just a tweet. (E.g. is it just industrial emissions? Is agriculture considered? Is it [not] considering absorption effects in forests etc.?) Are there some papers that explain/detail it? (And this might take us off the narrow Skeptics path, but is it still true in a per-capita graph? For example, when one considers the current yearly [thus not historically cumulative] emissions, the top per-capita looks very different than than the top per countries as a whole. Basically, is the claim technically true but misleading in some important way? [As a side note: a recent similar question here about climate-change claims is basically along the same broad lines as this last sub-question of mine, i.e. asking if we considered all the angles, not just the claim itself.])
